15 Claims.

This invention relates to shoemaking machinery and is illustrated as embodied in a machine for use in assembling loose insoles and prcmolded back parts of shoes.

In the manufacture of open shank shoes, for 1 example, it is common practice to build up separately the back parts of the uppers of the shoes and thereafter to mold them to their finished shape. Each of the premolded back parts is then positioned with relation to an insole secured to the bottom of a last and is thereafter permanently secured to the insole by fastenings which are arranged in the form of a letter U and are driven through a heel-seat flange oi the back part and the margin of the heel portion 1 of the insole.

Improved methods of assembling premolded back parts and unattached insoles are disclosed in application for United States Letters Patent Serial No. 396,902, filed June 6, 1941, in my name. In practicing the method disclosed in said application Serial No. 396,902, the operator staples the forward ends of a heel-seat flange of the back part to opposite lateral margins of the insole heel portion of the insole is inclined lengthwise at a slight angle to a general plane in which the U-shaped base crease of the back part lies, the rear end of the insole at this time being spaced a substantial distance from the heel-seat flange and being in approximate engagement with the rear end of the inside face of the upstanding portion of the back part. The heel portion of the insole is then forced against the entire inside face of the heel-seat flange of the back part, causing the edge of the heel portion of the insole to be forced snugly against the entire base crease of the back part, with the result that an outer base or break line portion of the back part is conformed to the outline of the heel portion of the insole. While the insole is thus forced against the heel-seat flange of the back part, a U-shaped line of tacks is driven through the hcehseat flange and the insole by a machine similar to that disclosed in application for United States Letters Patent Serial No. 396,901, filed June 6, 1941, in my name, in order permanently to secure the insole and the back part together.

To position insoles and back parts of shoes relatively to each other in the inclined relation above described and to present them while so positioned to a fastening inserting machine, preparatory to securing the insoles permanently to the back parts by a U-shaped row of tacks, requires considerable time. Moreover, it has been found that when the assembling of the insole and the back part is left entirely to the judgment and skill of the operator, the edge of the heel portion of the insole is frequently not effectively forced, as desired, against the base crease of the back part during the subsequent operation in which the heel portion of the insole is forced against theinner face of the heel-seat flange of the back part.

With the above considerations in View, it is an object of the present invention to provide in a fastening inserting machine a device by the use of which premolded back parts and insoles of shoes may be assembled as well as presented quickly and accurately to fastening inserting mechanism of the machine.

With the above object in View and in accordance with a feature of the present invention, the illustrative machine comprises means for relatively positioning a premolded back part and an insole of a shoe with the forward ends of an inside face of a heel-seat flange of the back part in engagement with the insole and the rear end of the insole in approximate engagement with an upstanding portion of the back part and spaced a substantial distance from the heel-seat flange of the back part, and fastening inserting mechanism, said means and said mechanism being mounted for relative movement to facilitate the presentation of the forward ends of the heel-seat flange of the back part and adjacent portions of the insole to said mechanism.

The illustrative machine comprises a plate upon which the heel portion of an insole is positioned bottom up by a pair of abutments, and a pair of gages having edges which are arranged substantial distances above and overlie the rear portion of the insole positioned upon the plate, said edges being shaped and arranged to be engaged by the rear portions of a base crease of a shoe back part, which is positioned upside down abutments and gages being arranged in nested relation, each of the gages extending above and over a corresponding abutment. The turret is mounted for swinging movement upon a pedestal which is slidable from an operative posiiion adjacent to fastening inserting mechanism to a work discharge position located some distance from said mechanism, the pedestal being normally held in its inoperative position against a stop by a spring.

After the insole and the premolded back part have been positioned as above described, the operator presses the opposite lateral wings of the back part toward each other, causing the opposite forward ends of the base crease of the back part to be forced against adjacent lateral edges of the insole, and then swings the turret, together with the work positioned thereon, until one forward end of the heel-seat flange of the back part is located below a fastening inserting nozzle and above a fastening clenching anvil of the machine. A fastening is then driven through the forward end of the heel-seat flange of the back part and through the insole to secure these parts together. The turret is then swung by the operator in an opposite direction to arrange the other forward end of the heel-seat flange of the back part positioned upon the insole beneath the nozzle, after which fastenings are driven through such forward end of the heel-seat flange and the insole.

In order to facilitate the removal of the assembled back part and insole from the machine, there is provided mechanism for swinging the work supporting plate into a raised position with reference to the turret so that the rear end of the plate will override the edges of the back part positioning gages when the pedestal is moved to its work discharge position.

By the use of the above device insoles and back parts of shoes can be quickly and effectively assembled in the above-mentioned relation preparatory to the subsequent permanent securing of these parts together by a U-shaped line of tacks driven through the heel-seat flange of the back part and through the insole.

The above and various other features of the invention will be understood and appreciated from the following detailed description read in connection with the accompanying drawings, in which Fig. 1 is an angular view of an illustrative device for use in assembling insoles and premolded back parts of shoes;

Fig. 9 is a perspective view, partly broken away, of a finished shoe in which the assembled back part and insole of Fig. 8 have been incorporated.

In practicing the method disclosed in the above-mentioned application Serial No. 396,902, a premolded back part 29 which is to form part of an open shank shoe 22 (Fig. 9) is arranged upon an insole 24 in a predetermined position, which will appear later, and is attached thereto by staples 23 (Figs. 6, '7 and 8) or other suitable fastenings which are driven through the heel end of the insole and the forward end portions of an inturned heel-seat flange 28 of the back part.

The illustrative back part 20 comprises a fiber counter 30 (Figs. 5, 7 and 8), a leather outer 32, and a thin leather lining 34, said parts being assembled and sewed and/or cemented together while flat and afterwards being molded to the shap shown in Fig. 4, to provide the heel-seat flange 28 to which the insole is attached, and an upstanding or heel band portion 36 which, in the finished shoe, encircles the heel of the wearer. The illustrative insole 24 comprises a fiber blank 38 to which is secured by cement and/or staples a stiff fiber shank and heel piece 46, and a fabric or leather binding strip 42 which is wrapped about and is sewed to the edge portions of the blank and the shank and heel piece and the edge of which, as illustrated in Fig. 9, is exposed to view in the finished shoe 22.

For reasons explained in said application Serial No. 396,902, it is desirable to secure the back part 20 to the insole 24 by the staples 26 while the forward ends of a crease 44, which is formed between the upstanding portion 36 and the heel-seat flange 28 of the back part and may be referred to as a base crease, are forced against the opposite lateral edges of the insole, as illustrated in Fig. 5, and a planar heel portion 46 of the insole is inclined at a slight angle to a general plane in which the heel-seat flange 28 and the U-shaped base crease 44 lie, the rear end of the insole 24 being spaced a substantial distance from the heel-seat flange, as indicated by reference numeral 49 (Figs. 5 and 7), and being in approximate engagement with a rear portion 48 (Figs. 5, 7 and 8) of the inside surface of the upstanding portion 36 of the back part. During this stage of the assembly of the back part 29 and the insole 24, the rear end of the insole is usually in engagement with the inside face of the upstanding portion 36 of the back part and the term approximate engagement is intended to include this arrangement.

It is highly desirable for reasons set forth in said application Serial No. 396,902, that in the finished shoe the entire base crease 44 of the back part 20 shall be in snug engagement with an edge 50 of the heel portion 46 of the insole of the shoe. It is common practice to incorporate premolded back parts 20 of the same size and shape in shoes of slightly different sizes and/or styles. Since the heel portions 46 of insoles 24 of shoes vary in size and shape in accordance with the sizes and styles of the shoes, it will be appreciated that in order to cause the base crease 44 of the back part to be brought into snug engagement with the edge 50 of the heel portion 46 of the insole 24 preparatory to securing the insole permanently to the back part, a base rim portion of the back part (that is, a portion of the back part in the vicinity of a break line 5|, Figs. 5, 7 and 8, of the back part) usually has to be flexed to a considerable extent. In practicing the method disclosed in said application Serial No.

396,902, the operator, after securing the back part 28 to the insole 24, as above described and as illustrated in Fig. '7, by the use of staples 26, causes, by the use of a modified heel-seat lasting machine such as disclosed in said application Serial No. 396,981, the margin of the heel portion 48 of the insole 24 to be forced with considerable pressure against an inner face 52 (Fig. 4) of the heel-seat flange 28 of the back part, the entire base crease 44 of the back part being forced into snug engagement with th edge 58 of the heel portion 48 of the insole and being conformed to an outline similar to that of such edge. The base rim portion of the back part 28 may thus be described as being conformed during the above operation to an outline similar to that of the edge 58 of the heel portion 46 of the insole, the break line 5I being substantially continuous with the lateral edges of the shank portion of the insole and merging gracefully therewith. While the insole 24 and the heel-seat flange of the back part 28 are thus forced or clamped together, a plurality of tacks 56 (Fig. 8) arranged in the form of a letter U are driven through the heelseat flange of the back part and the heel portion of the insole in order permanently to secure to-- gether the back part and the insole. By practic ing the above method, back parts 28 may be assembled with and permanently secured to insoles 24 quicker and more accurately than has heretofore been possible.

In order to position the back part 28 with reference to the insole 24, as above described, preparatory to stapling together the back part and the insole, there is provided a work support or device 58 (Fig. 1) which comprises a pedestal 68 a base portion 82 of which fits in a guideway 64 of a supporting bracket 86 fixed to a main frame of a staple driving machine such, for example, as disclosed in United States Letters Patent No. 1,557,561, granted October 28, 1925, on an application filed in the name of John W. Cosgrove, the arrangement being such that the pedestal may be moved from an operative position (shown in full lines in Fig. l), in which it is in engagement with a stop face 88 and is located adjacent to a nozzle I8 of a staple driving unit (not shown) and adjacent to a fastening clenching anvil I2 secured by screws I4 to the bracket 68, to an unloading position (shown by dash lines in the shank I8 of the turret I8 is a vertical slot 86 which is wider than the diameter of the retaining pin 82, the arrangement being such that the turret may be quickly removed from the pedestal 68 by rotating the turret 180 about an axis 81 of the shank I8 from its operative position shown in Fig. 1, and then lifting the turret from the pedestal.

Mounted upon the turret I8 is a sole supporting plate 88 having at its rear end notches 88 (Figs. 1, 2 and 3) and at its forward end a depending apron 82 (Fig. 2) which is pivoted upon a fulcrum pin 94 secured to the turret. Fitting in a Y-shaped groove 86 (Fig. 3) in the upper face of th turret I6 and riveted to said turret is a gage 98 having a pair of upstanding abutments or lugs I88 which extend through the notches 88 of the plate 88 and are shaped and arranged to be engaged by the rear end of the insole 24 and to position the insole lengthwise and widthwise upon the plate. Formed integral with the gage 88 is a flexible flange I82 (Fig. 2) which is constantly forced against the apron 92 of the plate 88, the arrangement being such that the plate is normally held in engagement with an upper surface I84 (Figs. 1 and 3) of the turret I8 but may be swung in a clockwise direction, as viewed in Fig. 1, about the pivot pin 88, by mechanism which Will appear later, to facilitate the removal of the work from the machine.

Arranged between an upper surface I88 (Fig. 2) of the pedestal 68 and the bottom of a shallow depression I88 in the bottom of the turret i6 is a gage H8 having an upstanding block I I2 (Figs. 1, 2 and 3) which fits in an elongated guideway H4 of the turret and into which is threaded an adjusting screw H8. The end of the screw H8 is normally forced against an end face H8 (Figs. 1 and 3) of the guideway H4 through the provision of a spring I28 (Fig. 2) which is arranged in a recess I22 of the turret and has its opposite ends in engagement with the turret and an upstanding flange I24 at the forward end of the gage H8. Formed in the gage II 8 is an elongated slot I26 through which passes the shank I8 of the turret I8, said gage having at its rear end a pair of upstanding abutments or lugs I28 the upper edges I 38 of which are usually arranged just above and slightly forward of corresponding abutments I88 and are shaped and ar- 1 ranged to be engaged by the rear portions of the base crease 54 of the back part 28 in order to facilitate the positioning of the back part upon the insole 24, as illustrated in Fig. 5. The abutments I28 may be initially moved into different operative positions lengthwise of the insole by turning the screw I IS.

The turret I8 is normally held in its neutral position, shown in Fig. l, in which a central plane I82 of the turret is arranged approximately parallel to the guideway 84 of the bracket 86, by a spring I34 the upper and lower ends of which are secured to the turret and to an extensihn I36 of the pedestal. The pedestal 88 is constantly urged to its operative position (shown in full lines in Fig. 1) against the stop face 88 by a spring I38 opposite ends of which are connected to the bracket 68 and the pedestal 68, the sole supporting plate 88 at this time being arranged adjacent to the fastening inserting nozzle I8 and to the fastening clenching anvil I2.

In assembling the premolded back part 28 and the loose insole 2-8, the operator places the heel portion 48 of the insole bottom up on the plate 88 with the rear end of the insole in engagement with the abutments I88 and then positions the back part over the heel end of the insole, as illustrated in Fig. 5, with the rear portion of the base crease d8 of the back part in engagement with 1e upper edges I38 of the abutments I28, the forward ends of the base crease being moved into engagement with the opposite lateral edges of the insole by the operator. Should one lateral portion or wing of the back part 28 project forwardly of the other, the back part is shifted by the operator to a slight extent circumfcrentially of the heel part of the insole until the forward ends of the heel-seat flange 28 are arranged opposite each other. When the insole 28 and the back part 28 are thus positioned upon the support, the general plane of the heel portion 48 of the insole is inclined lengthwise to the general plane which includes the base crease 44, the rear end of the insole being spaced rearwardly of and a substantial distance from the heel-seat flange 28 and being in approximate engagement with the rear inside face GS of the upstanding portion 36 of the back part. The operator then swings the turret "F6, together with the work mounted thereon, in one direction about the axis 81 (Fig. 2) to move one of the forward ends of the heelseat flange 28 directly beneath the fastening inserting nozzle IQ and over the clenching anvil I2. A treadle (not shown) is then depressed, causing fastening inserting mechanism (not shown) to be operated, thereby driving one or more staples through the heel-seat flange 28 of the back part 20 and through the heel portion of the insole 24. The turret To and the work mounted thereon are then swung in an opposite direction about the axis 87 to move the opposite end of the heel-seat flange 28 to a position beneath the fastening inserting nozzle III and over the anvil i2 preparatory to driving staples 25 through the opposite end of the heel-seat flange and the insole.

After the insole 24 and the back part 20 have been stapled together as shown in Fig. 7, it will be appreciated that the rear end of the insole is spaced a substantial distance from the end of the heel-seat flange 28 of the back part. Moreover, the edges I36 of the abutments I28 overlie and extend slightly forward of the rear portions of the insole 23. Accordingly, it is desirable, preparatory to removing the assembled insole and back part from the machine, to swing or tilt the plate 88 in a clockwise direction, as viewed in Fig. 1, about the fulcrum pin Il i (Fig. 2) until the rear end of the plate, together with the rear end of the insole mounted thereon, is raised slightly above the upper edges I36 of the abutments I28, thereby enabling the operator to slide the assembled insole and back part rearwardly from the plate.

In order to tilt the plate 88 upwardly as above described, there is provided a rod me which is guided for movement in a cylindrical recess I42 of the pedestal 66. The upper end portion of the rod Mil passes through a recess I44 in the shank portion 78 of the turret l6 and, when the pedestal I!) is in its operative position, is arranged just below the bottom face of the plate 88. In order to raise the rod I40 and therefore to swing the plate 88 in a clockwise direction (Fig. 1) as the pedestal is moved to the left from its full line position adjacent to the fastening inserting nozzle 19, there is provided a bifurcated lever M5 the forward end of which is pivoted upon a fulcrum pin I 38 carried by the base portion 82 of the pedestal Bil. Arms of the bifurcated lever Hi6 are provided with faces I50 which are constantly engaged by a pin I52 secured to the rod I40 and extending through elongated slots I54 formed in the opposite sides of the pedestal $0. Mounted upon the arms of the bifurcated lever I48 are rolls I56, the arrangement being such that when the pedestal is moved to the left, as viewed in Fig. 1, along the guideway 65, the rolls I56 slide up inclined ramps or cams I58 of the bracket I56, causing the rod I49 to be raised and the plate 88 to be swung to its dash line position shown in Fig. 1. With such an arrangement the operator, after assembling the insole 24 and the back part 2%, slides the pedestal to the left along the guideway 64 to move the heel end of the assembled insole and back part from beneath the nozzle ID. The work is then slid heel end first from the work support, which is then released and under the action of the spring I38 returns to its operative position.

In order to vary the distance between the rear end portions of the plate 88 and the upper edges I30 of the abutments I28 in accordance with the thickness of the insole and the desired angle between the plane of the heel portion 45 of the insole and the general plane of the base crease 44, the initial operative position of the plate 88 may be varied through the provision of a screw I60 which is threaded into one of the arms of the bifurcated lever I56 and the lower end of which engages the bracket 66.
